Bought a power meter from a China DIYer cost @$60

With full CNC shell and impresionante weight…

I don't know how accurate it is but I will compare it with my quarq dzero/force/rival spindle PM/p2m ng eco soon. The manufacturer had tested it before so I expect a not bad result. But considering the price I wouldn't complain anything.

Direct mount 3-bolt compatible, 110bcd 4bolt chainring. The manufacturer also made a Easton cinch version.

Hope he would make a 104bcd version some day for my XC plan… haha

EDIT
No, it is not a april fool joke. and i just wnat to share you some new incredibly cheap gigs from some random chinese guy.

for more informacion about it:

Actually, this DIYer runs a private WeChat group of about 200 members and hasn't gone public yet. Honestly, it might never go public—it seems more like an undergraduate guy having some fun and earning a bit of pocket money. He handles the PCB fabrication through JLC (the global leader in PCB prototyping) himself instead of relying on a generic OEM provider. I’m still waiting on a new frame to test it, but his internal test results look solid.

Personally, I much prefer this custom spider-based design over surface-mounted ones. At the end of the day, power meters are essentially just fancy electronic scales—it's all just strain gauges anyway. I ran a 4iiii single-sided unit on my R8120 for about 3000km and it just sucks, haha.

As for the charging port, it’s likely just a generic 10cent part from 1688. Big brands and DIYers alike use these off-the-shelf components to avoid high tooling costs.
